 THIS SHARE PURCHASE AGREEMENT, dated as of June 29, 2018 (this
“Agreement”), is made by and between Athenex, Inc., a company incorporated under the laws of the State of Delaware (the “Company”) and Perceptive Life Sciences Master Fund, Ltd., a Cayman Islands exempted company
(the “Investor”). 
 RECITALS: 

A. The Investment. The Investor intends to subscribe for and purchase from the Company, and the Company intends to issue and sell to
the Investor, as an investment in the Company, the securities as described herein. The securities to be purchased at the closing are shares of common stock, par value $0.001 per share, of the Company (“Common Stock”). 

B. Exemption from Securities Registration. The Parties are executing and delivering this Agreement in reliance upon the exemption from
securities registration afforded by Section 4(a)(2) of the U.S. Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (the “Securities Act”) and the provisions of Regulation D or other
applicable exemptions from registration, as promulgated by the U.S. Securities and Exchange Commission under the Securities Act. 
 C.
Registration Rights Agreement. At the Closing, the Company and the Investor will enter into a Registration Rights Agreement, substantially in the form attached as Exhibit C hereto (the “Registration Rights Agreement”),
pursuant to which the Company has agreed to provide certain registration rights with respect to the Purchased Shares issued and sold to the Investor, under the Securities Act and applicable state securities laws. 

D. Warrant. As of the date hereof, the Company and the Investor have entered into a Warrant (the “Warrant”), pursuant
to which the Company has agreed to issue to the Investor a warrant with the right to purchase a number of shares of Common Stock subject to the terms and conditions as set forth therein. 

E. Transaction Documents. The term “Transaction Documents” refers to this Agreement, the Registration Rights Agreement
the Warrant and each of the other agreements and documents entered into or delivered by the parties hereto in connection with the transactions contemplated hereby or thereby.

the parties agree as follows: 
 ARTICLE I 

PURCHASE; PURCHASE PRICE; AND CLOSINGS 

SECTION 1.1. Purchase. On the terms and subject to the conditions set forth herein, the Investor will purchase from the Company, and
the Company will issue and sell to the Investor, such number of shares of Common Stock equal to the quotient resulting from dividing the Aggregate Purchase Price by the Purchase Price Per Share, rounded down to the nearest whole share of Common
Stock (such shares of Common Stock collectively, the “Purchased Shares”). 







 SECTION 1.2. Purchase Price. The purchase price per Purchased Share (the “Purchase

on NASDAQ, for the ten (10) Trading Days immediately prior to the date hereof (including the date hereof). The parties agree that the aggregate purchase price (the “Aggregate Purchase Price”) shall be US$50,000,000.
“VWAP” means, for any date, the price determined by the daily volume weighted average price of shares of the Common Stock for such date (or the nearest preceding date) on NASDAQ (based on a Trading Day from 9:30 a.m. (New York City
time) to 4:00 p.m. (New York City time)). “Trading Day” means a day on which shares of the Common Stock are listed or quoted and traded on NASDAQ.

the consummation of the Borrowing under the Credit Agreement (the date on which the Closing actually occurs, the “Closing Date”). At the Closing, the Investor shall (i) pay to the Company the Aggregate Purchase Price by wire
transfer of immediately available funds in United States dollars to a bank account designated by the Company, and (ii) deliver to the Company a copy of the Registration Rights Agreement duly executed by the Investor. At the Closing, the Company
shall (i) deliver to the Investor a true and complete copy of the duly passed resolutions of the board of directors of the Company (in the form of minutes or otherwise), or the relevant extracts thereof, evidencing approval of the execution,

the Registration Rights Agreement duly executed by the Company. On the Closing Date, the Company shall instruct the transfer agent for the Common Stock (the “Transfer Agent”) to promptly credit the Investor the Purchased Shares
(and, upon request of such Investor, shall instruct the Transfer Agent to deliver stock certificates to the Investor representing the Purchased Shares), 

SECTION 1.4. Closing Conditions. 

(a) The obligation of the Investor to consummate the Closing is subject to the fulfillment prior to or contemporaneously with the Closing of

such representations and warranties shall be true in all respects); 
 (iii) the Company shall have performed in all material
respects all obligations required to be performed by it at or prior to or contemporaneously with the Closing under this Agreement;

ARTICLE II 

REPRESENTATIONS AND WARRANTIES 

SECTION 2.1. Representations and Warranties of the Company. The Company represents and warrants to the Investor as of the date hereof
and as of the Closing Date (except to the extent made only as of a specified date, in which case as of such date) that, except as set forth in the reports, registrations, documents, filings, statements, schedules and submissions together with any
required amendments thereto filed with the U.S. Securities and Exchange Commission (the “SEC”) prior to the date of this Agreement (the “SEC Documents”): 

(a) Organization and Good Standing. The Company and each other Group Company have been duly organized and are validly existing and in
good standing (or the jurisdictional equivalent) under the laws of their respective jurisdictions of organization, are duly qualified to do business and are in good standing (or the jurisdictional equivalent) in each jurisdiction in which their
respective ownership or lease of property or the conduct of their respective businesses requires such qualification, and have all power and authority necessary to own or hold their respective properties and to conduct the businesses in which they
are engaged, except where the failure to be so qualified or in good standing or have such power or authority would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 

(b) Due Authorization. The Company has full right, power and authority to execute and deliver the Transaction Documents and to perform
its obligations thereunder; and all action required to be taken for the due and proper authorization, execution and delivery by it of the Transaction Documents and the consummation by it of the transactions contemplated thereby has been duly and
validly taken. The Transaction Documents constitute the legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
moratorium and similar laws of general applicability, relating to or affecting creditors’ rights generally and to general equitable principles. 

(c) Capitalization. As of the date of this Agreement, (a) the authorized share capital of the Company is US$275,000,000, and

 4 








 
emptive rights), warrants, or instruments convertible into or exchangeable for, any shares of capital stock or other equity interests in the Company or any of its subsidiaries, or any contract,
commitment, agreement, understanding or arrangement of any kind relating to the issuance of any capital stock of the Company or any such subsidiary, any such convertible or exchangeable securities or any such rights, warrants or options; and
(d) all of the outstanding shares of capital stock or other equity interests of each material subsidiary owned, directly or indirectly, by the Company have been duly and validly authorized and issued, are fully paid and non-assessable and are owned directly or indirectly by the Company, free and clear of any lien, charge, encumbrance, security interest, restriction on voting or transfer or any other claim of any third party
(“Encumbrances”). The issuance and sale of the Purchased Shares hereunder will not obligate the Company to issue shares of Common Stock or other securities to any other Person (other than the Investors) and will not result in the
adjustment of the exercise, conversion, exchange or reset price of any outstanding security. 
 (d) Valid Issuance. The Purchased
Shares to be issued and sold by the Company hereunder have been duly authorized and, when issued and delivered and paid for as provided herein, will be duly and validly issued, will be fully paid and
non-assessable, and shall be free and clear of Encumbrances (other than those created by the Investor), except for restrictions on transfer imposed by applicable securities laws. 

(e) No Violation or Default. Neither the Company nor any other Group Company is (i) in violation of its charter or by-laws or similar organizational documents; (ii) in default, and no event has occurred that, with notice or lapse of time or both, would constitute such a default, in the due performance or observance of any
term, covenant or condition contained in any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any other Group Company is a party or by which the Company or any other Group Company is bound
or to which any property or asset of the Company or any other Group Company is subject; or (iii) in violation of any law or statute, including laws of foreign jurisdictions, tax laws, environmental protection laws, health and pharmaceutical
regulatory laws, social security laws or labor laws, or any judgment, order, rule or regulation of any court or arbitrator or governmental or regulatory authority, except, in the case of clauses (ii) and (iii) above, for any such default or
violation that would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 
 (f) No
Conflicts. The execution, delivery and performance by the Company of the Transaction Documents, the issuance and sale of the Purchased Shares and the consummation of the transactions contemplated by the Transaction Documents will not
(i) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, result in the termination, modification or acceleration of, or result in the creation or imposition of any lien, charge or
encumbrance upon any property, right or asset of the Company or any other Group Company pursuant to, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any other Group Company is a party
or by which the Company or any other Group Company is bound or to which any property, right or asset of the Company or any other Group Company is subject, (ii) result in any violation of the provisions of the charter or by-laws or similar organizational documents of the Company or any other Group Company or (iii) result in the violation of any law or statute or any judgment, order, rule or regulation of any court or arbitrator
or governmental or regulatory authority, except, in the case of clauses (i) and (iii) above, for any such conflict, breach, violation or default that would not, individually or in the aggregate, reasonably be expected to have a Material Adverse
Effect.

 (g) No Consents Required. Assuming the accuracy of the representations and warranties of
the Investor set forth in SECTION 2.2, no consent, approval, authorization, order, registration or qualification of or with any court or arbitrator or governmental or regulatory authority is required to be made or obtained by the Company for the
execution, delivery and performance by the Company of this Agreement, the issuance and sale of the Purchased Shares and the consummation of the transactions contemplated by the Transaction Documents, except for those that have been made or obtained
prior to the date hereof, post-Closing filings pursuant to securities laws and the rules and regulation of The NASDAQ Stock Market LLC, which the Company shall file within the applicable time periods and the registration of the Purchased Shares
under the Securities Act as and when required under the Registration Rights Agreement. 
 (h) Financial Statements. As of their
respective dates, the financial statements (including the related notes thereto) of the Company and its consolidated subsidiaries included in the Company’s Annual Report on Form 10-K for the year ended
December 31, 2017, as filed with the SEC on March 26, 2018 comply in all material respects with the applicable requirements of the Securities Act and present fairly the financial position of the Company and its consolidated subsidiaries as
of the dates indicated and the results of their operations and the changes in their cash flows for the periods specified; such financial statements have been prepared in all material aspects in conformity with generally accepted accounting
principles (“GAAP”) in the United States applied on a consistent basis throughout the periods covered thereby, and any supporting schedules included in the SEC Documents present fairly in all material aspects the information
required to be stated therein; and the other financial information included in the SEC Documents has been derived from the accounting records of the Company and its consolidated subsidiaries and presents fairly in all material aspects the
information shown thereby. 
 (i) Regulatory Filings. Except as would not, individually or in the aggregate, reasonably be expected to
have a Material Adverse Effect, neither the Company nor any other Group Company has failed to file with the regulatory authorities any required filing, declaration, listing, registration, report or submission with respect to the product candidates
of the Company or the other Group Companies that are described or referred to in the SEC Documents; all such filings, declarations, listings, registrations, reports or submissions were in material compliance with Applicable Laws when filed; and no
material deficiencies regarding compliance with Applicable Law have been asserted by any applicable regulatory authority with respect to any such filings, declarations, listings, registrations, reports or submissions. 

(j) Title to Real and Personal Property. The Company and the other Group Companies have good and marketable title in fee simple to, or
have valid rights to lease or otherwise use, all items of real and personal property that are material to the respective businesses of the Company and the other Group Companies, in each case free and clear of all Liens, except those that (i) do
not materially interfere with the use made and proposed to be made of such property by the Company and the other Group Companies or (ii) would not, individually or in the aggregate, reasonably be excepted to have a Material Adverse Effect. 


  
 6 








 (k) Tax. The Company and the other Group Companies have paid all federal, state, local and
foreign taxes and filed all tax returns required to be paid or filed through the date hereof except where such failure to pay or file would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; and except
as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, there is no tax deficiency that has been, or could reasonably be expected to be, asserted against the Company or any other Group Company or any
of their respective properties or assets. To the Company’s knowledge, no tax investigation is currently pending against the Company or any other Group Company. The provisions included in the financial statements as set out in the SEC Documents
included appropriate provisions required under U.S. GAAP for all taxation in respect of accounting periods ended on or before the accounting reference date to which such audited accounts relate for which the Company was then or might reasonably be
expected thereafter to become or have become liable. 
 (l) Absence of Certain Changes. Since the date of the most recent financial
statements of the Company included in the SEC Documents, (i) there has not been any change in the capital stock (other than the issuance of Common Stock upon exercise of any stock options and warrants described as outstanding in, and the grant
of any options and awards under existing equity incentive plans described in, the SEC Documents), short-term debt or long-term debt of the Company or any other Group Company, or any dividend or distribution of any kind declared, set aside for
payment, paid or made by the Company on any class of capital stock, or any other change or development that, individually or in the aggregate, has had or would reasonably be expected to have a Material Adverse Effect, (ii) neither the Company
nor any other Group Company has entered into any transaction or agreement (whether or not in the ordinary course of business) that is material to the Company and the other Group Companies taken as a whole or incurred any liability or obligation,
direct or contingent, that is material to the Company and the other Group Companies taken as a whole (other as described in the SEC Documents); (iii) there has not been any material damage, destruction or loss, whether or not covered by insurance to
any assets or properties of the Company or any Group Company, that, individually or in the aggregate, has had or would reasonably be expected to have a Material Adverse Effect, (iv) there has not been any material labor difficulties or labor
union organizing activities with respect to employees of the Company or any Group Company that, individually or in the aggregate, has had or would reasonably be expected to have a Material Adverse Effect, and (v) there has not been any other
event or condition of any character that has had or could be reasonably expected to have a Material Adverse Effect.

Company, any other Group Company or any directors, director nominees or executive officers (in their respective capacities as such) of any Group Company is a party or to which any property of the Company or any other Group Company is the subject
that, individually or in the aggregate, if determined adversely to the Company or any other Group Company, would reasonably be expected to have a Material Adverse Effect; (ii) no such Actions are, to the knowledge of the Company, threatened;
(iii) there are no prior, current or pending Actions that are required under the Securities Act to be described in the SEC Documents that are not so described in the SEC Documents, and (iv) there are no statutes, regulations or contracts
or other documents that are required under the Securities Act to be filed as exhibits to the SEC Documents or described in the SEC Documents that are not so filed as exhibits to the SEC Documents or described in the SEC Documents.

 (n) Material Contracts. Each franchise, contract or other document of a character required
to be described in the SEC Documents or to be filed as an exhibit to the SEC Documents under the Securities Act and the rules and regulations promulgated thereunder is so described or filed. All such agreements and contracts are valid, binding, in
full force and effect and enforceable against each of the parties thereto. Neither the Company, nor, to the Company’s knowledge, any other party thereto, is in material default of any of its obligations under any such agreement or contract.

 (o) Licenses and Permits. The Company and the other Group Companies possess, and are in material compliance with the terms of, all
material licenses, certificates, permits and other authorizations issued by, and have made all declarations and filings with, the appropriate federal, state, local or foreign governmental or regulatory authorities that are necessary for the
ownership or lease of their properties or the conduct of their business as described in the SEC Documents, except where the failure to possess or make the same would not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect; and neither the Company nor any other Group Company has received notice of any revocation or modification of any such material license, certificate, permit or authorization or has any reason to believe that any such material license,
certificate, permit or authorization will not be renewed in the ordinary course except as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The Company and the other Group Companies (i) are,
and at all times since January 1, 2017 have been, in compliance with all statutes, rules and regulations applicable to the ownership, testing, development, manufacture, packaging, processing, use, distribution, storage, import, export or
disposal of any product manufactured or distributed by the Company (“Applicable Laws”); and (ii) have not received any U.S. Food and Drug Administration Form 483, written notice of adverse finding, warning letter, untitled
letter or other correspondence or written notice from any court or arbitrator or governmental or regulatory authority alleging or asserting non-compliance with (x) any Applicable Laws or (y) any
licenses, exemptions, certificates, approvals, clearances, authorizations, permits and supplements or amendments thereto required by any such Applicable Laws except in each case of clause (i) and clause (ii), as would not, individually or in
the aggregate, reasonably be expected to have a Material Adverse Effect. Without limiting the generality of the foregoing, all preclinical and clinical studies conducted by or, to the Company’s knowledge, on behalf of the Company to support

the terms and conditions contemplated by this Agreement. 
 (g) Sophisticated Investor. The Investor is knowledgeable, sophisticated

failure of any 

  
 18 








 
Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this SECTION 4.3 unless and to the extent that the Indemnifying Party shall

unreasonably withheld or delayed), settle or compromise any claim or consent to entry of any judgment in respect thereof in any pending or threatened action, suit, claim or proceeding in respect of which indemnification has been sought hereunder
unless such settlement or compromise includes an unconditional release of such Indemnified Party from all liability arising out of such action, suit, claim or proceeding. 

(d) In calculating the amount of any Losses hereunder, there shall be subtracted the amount of any insurance proceeds and third-party payments
received by the Indemnified Parties with respect to such Losses, if any, net of any actual costs or expenses incurred in connection with securing or obtaining such proceeds or payments. In no event shall any Indemnified Party be entitled to recover
or make a claim for any amounts in respect of, and in no event shall “Losses” be deemed to include, consequential or indirect damages, lost profits or punitive damages and, in particular, no “diminution of value”, “multiple
of profits” or “multiple of cash flow” or similar valuation methodology shall be used in calculating the amount of any Losses, unless in any such case, such Losses are awarded to a third party. 

(e) Absent a showing of fraud by a party, and assuming the Closing has occurred, the indemnification obligation of a party under this SECTION
4.3 shall be the sole and exclusive remedy of any other party against such party for monetary damages for breach of any representation, warranty, covenant or agreement contained in this Agreement or any of the transactions contemplated hereby.
Nothing herein shall limit a party’s right to seek injunctive or other equitable relief in connection with the enforcement of this Agreement. 

  
 19 








 (f) Any indemnification payments pursuant to this SECTION 4.3 shall be treated as an adjustment
to the investment amount for the Purchased Shares for U.S. federal income and applicable state and local tax purposes, unless a different treatment is required by applicable law. 

SECTION 4.4. Registration Rights. At the Closing, the Company, the Investor and the other parties thereto will each enter into the

signed by an officer of a duly authorized representative of such party. 
 SECTION 6.3. Waivers. No failure or delay by any party in

SECTION 6.10. Captions. The article, section, paragraph and clause captions herein are for convenience of reference only, do not
constitute part of this Agreement and will not be deemed to limit or otherwise affect any of the provisions hereof. 
 SECTION 6.11.
Severability. If any provision of this Agreement is found to be invalid or unenforceable, then such provision shall be construed, to the extent feasible, so as to render the provision enforceable and to provide for the consummation of the
transactions contemplated hereby on substantially the same terms as originally set forth herein, and if no feasible interpretation would save such provision, it shall be severed from the remainder of this Agreement, which shall remain in full force
and effect unless the severed provision is essential to the rights or benefits intended by the parties. In such event, the parties shall use commercially reasonable efforts to negotiate, in good faith, a substitute, valid and enforceable provision.

 SECTION 6.12. No Third-Party Beneficiaries. Nothing contained in this Agreement, expressed or implied, is intended to confer or
shall confer upon any person other than the express parties hereto, any benefit, right or remedies. The representations and warranties set forth in Article II and the covenants set forth in Articles III and IV have been made solely for the benefit
of the parties to this Agreement and (a) may be intended not as statements of fact, but rather as a way of allocating the risk to one of the parties if those statements prove to be inaccurate; and (b) may apply standards of materiality in
a way that is different from what may be viewed as material by shareholders of, or other investors in, the Company. 
 SECTION 6.13.

applicable securities exchange, provided that the disclosing party shall, to the extent permitted by applicable law or any listing agreement with or requirement of the NASDAQ or any other applicable securities exchange, inform the other party about
the disclosure to be made pursuant to such requirements prior to the disclosure. 

  
 25

irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms. It is accordingly agreed that the parties shall be entitled to seek specific performance of the
terms hereof, this being in addition to any other remedies to which they are entitled at law or equity.
